See the URL or the listed bug in depends/blocks. Known issue in attempting to compile against alsa-lib-1.0, easy fix (patch included).
Created attachment 24257 [details, diff] Patch to define necessary symbols.
Hmm. just dawned on me people will likely castrate me if I don't give them some info regarding version for the patch... The patch is for 0.16.0; haven't tried it against all versions, although I would suspect it would apply cleanly (also would suspect they're all affected by this bug).
